I attempted an upgrade to the nightlies last night, and after the reboot, my install was in a critical state (failed update - I've attached the /data/update.failed log).  It seems as if the database for the jails infrastructure got borked.  No jails or plugins were started.  In fact any attempt to view the jails returned a database error. 
Is there anyway to recover from this?
